JOHN SKINNER, OF FLINT, ASSIGNOR OF ONE-HALF TO HENRY PU'IMAN, OFGOODRICH, MICHIGAN.

` BEAN SCOURER AND CLEANER.

SPECIFICATION forming part of Letters Patent No. 541,185, dated June 18,1895.

Application filed September 1, 1894:. Serial No. 521,896. (No model.)

To all whom it? may concern,.-

Be it known that I, JOHN SKINNER, a citizen of the United States,residing at Flint, in the county of Genesee and State of Michigan, haveinvented certain new and useful Improvements in Bean Scourers andCleaners, of which'the following is a specification, reference being hadtherein to the accompanying drawings.

xo The invention consists in the construction and arrangement kof ascouring cylinder and its scouring drum and further in its combinationwith separating mechanism, and the actuating and feed devices, all asmore fully f 5 hereinafter described.

In the drawings, Figure l is a vertical central section through myimproved machine. Fig. 2 is a horizontal section on line 0c, Fig. l.Fig. 3 is a vertical section at right angles 2o to Fig. l, illustratingthe construction of the cleaning and separating mechanism.

A is a suitable supporting frame. Centrally thereof is the squarecylinder-supporting frame Bin which is detachably supported the cylinderC. Below the cylinder is a cross bar Din which is journaled the stubshaft D on the lower end of the drum E, preferably a solid cylindricalbody. The upper end of this drum has the stub shaft F jour- 3o naled inthe cross bar G and provided with a bevel pinion H, with which meshesthe bevel gear wheel 1I on the crank shaft I, by means of which a rotarymotion may be imparted to the drum. The drum is of less diameter 5 5than the cylinder, and is covered with the textile cover .I backed bythe coil springs K which at their inner ends enter sockets in theperiphery of the drum, and at their outer ends bear against the cover J.This cover 4o has the concentric portions L and the eccentric sections Mextending down to the face of the drum, and forming vertical feedchannels, O.

P is a hopper arranged with its discharge over the periphery of thedrum, so that material fed therefrom will fall into the channels O, and'as the drum revolves will scour the same between the spring-backed coverand the cylinder gradually dropping by gravity to the lower end where itfalls from the 5o cylinder upon the screen Q. .This screen is inclinedand is reciprocated by the crank shaft Q driven by belt connection fromthe crank shaft I. From the screen the material is delivered on theseparator belt or apron R, driven by belt connection from the crankwheel I'.

The scouring cylinder drum will thoroughly scour the material, such asbeans, without in any way injuring it, and regardless of the size 6o ofthe material, that -is it will as thoroughly scour the small as thelarge beans.- Y

The screen separates the smaller broken particles from the good beansand the operator may separate the poor beans or dirtwhich may be withthe beans, as they are fed along on the belt R.

lVhat I claim as my invention isl. In a scouring machine, thecombination with the vertically disposed scouring cylin- 7c der, of adrum concentrically arranged within the cylinder, a flexible coversurrounding the drum, yielding means for normally forcing the coveringout of contact with the drum at opposite sides, depressions formed inthe v covering extending vertically the length thereof, means forrotating the drum and covering, and a feed hopper arranged in line withthe space between the drum and cylinder, substantially as described. 8o

2. In a-scouring machine, the combination with the vertically disposedscouring cylinder, of a rotary drum concentrically arranged within thecylinder, formed with a series of depressions in its periphery, a seriesof springs 8 5 seated in said depressions, a tiexible coveringsurrounding the drum and springs and connected to the drum between thesprings to form feed channels extending lengthwise of the drum, andmeans for feeding the grain 9o into the cylinder at a point between thesame and drum, substantially as described.

3. In a scouring machine, the combination of the imperforate verticalcylinder, a feed hopper discharging into the cylinder at the periphery,a rotary drum of less diameter than the cylinder, a vertically arrangedloose textile covering secured at points to the drum, spiral springssecured at their base to the druxn and pressing with their outer 5 endsagainst the textile covering, and means for rotating the drumsubstantially as described.

In testimony whereof I aftix my signature in presence of two witnesses.

JOHN SKINNER.
